Setup: HD HomeRun Extend for OTA broadcasts to two ATV's. Synology NAS.
On both ATV's the Channels DVR app opens to the problem screen, "There was a problem communicating with Channels DVR". Selecting "Try Again" doesn't work. The Channels Live TV app, however, works fine, including seeing my existing recordings. I might assume this is a subtle way of indicating that the DVR app is retired, except that the HD HomeRun app on my iPhone is also having trouble.
Going to 192.168.1.102:8089, I see "0 channels on 192.168.1.122". Scanning channels picks up the usual 20 OTA channels, but refreshing the screen continues to show 0 channels.
What might cause the DVR app to stop responding but the Live TV app to work fine?
